Hi there!

I'm a proud owner of a Samsung Galaxy S3 I9300 (bought in Israel) running 4.1.2 stock.
I've installed "Revolutionary S5 ROM V3" on it, but after a successful installation, the phone failed to recognize my SIM card, thinking there's no SIM card inside. I panicked and restored my NANDroid backup, and everything worked well, but how can I get Revolutionary S5 ROM (or any ROM for that matter) other than my stock ROM to recognize my SIM card?

By the way, I'm sorry I have to make a new thread about it rather than ask my question in the ROM's page, unfortunately it prevents me from doing so because of my low post count.

Thanks for your support!

Maybe an idea to search the threads before posting but since you asked nicely, http://forum.xda-developers.com/devd...ct/dl/?id=5942 here is the link to the updated modem, flash revolutionary s5 then flash this file in recovery and there shouldn't be any issues!

Thank you for your support! I swear I've been searching and haven't found an answer before though. Can you tell me about this file? What does it do? Is it reversible if I flash back to stock again?

OK what it does is it changes your EFS to V2 (anything before Android 4.3 used EFS v1 that's why you get no signal) http://forum.xda-developers.com/devd...ct/dl/?id=5557 download this app on to your phone (credits to Ricky) and then backup your current EFS.... And then flash the new one to use with all Roms that are Android 4.3 or higher but if you choose to revert to 4.1.2 for instance you will need your EFS V1 backup to get signal back, so basically backup, then flash rom (it's amazing) and then the file I posted earlier and stick with it!
